It definitely doesn’t help to have to fight against three of the four main U.S. mobile operators – Verizon, AT&T and T-Mobile – which are working on their own mobile payment operation called ISIS. That means Android handsets launched by these three carriers do not come with Google Wallet on board, which is quite a hassle for Android users that want to use the service.
Even Sprint, currently the only mobile operator that supports Google Wallet, wants to get itself its own mobile payment operation, although no new product announcements have been made in that regard yet.
Meanwhile, if you have purchased a Galaxy S3 from Verizon, and want to have Google Wallet up and running on the handset then we have good news for you: it can be done.
However, in order to get Google Wallet running on a Verizon Android handset with NFC capabilities such as the Galaxy S3, you’d have to root the device and install additional files. While we’re definitely not encouraging you to perform any tasks, it’s up to you to choose whether to have Google Wallet enabled on the Verizon Galaxy S3 or not.
